How to Grow Salsify in Warm Temperate Australia

- Deep, loose, stone-free soil. Dig to at least 30-40cm depth. Light sandy loam is ideal. Avoid heavy clay or stony soil which causes forked, stubby roots. Prepare with well-rotted compost dug in deeply.
- Salt
- Moderately sensitive. Copes with a little salt, but the harvest drops on salty bore water.
- pH Range
- 6.0-7.5
- Sunlight
- Full sun to light shade
- Spacing
- 12cm apart, 35cm between rows
- Watering
- Consistent moisture throughout the long growing season. Deep watering once or twice weekly. Irregular watering causes tough, woody roots.
- Good companions
- Dwarf Beans, Lettuce, Onion, Carrot, Spinach

- Fruiting crops (Tomato, Capsicum, Zucchini)
- Grow after it
- Legumes (Beans - Dwarf, Peas, Broad Beans)
Give the bed 3 turns before root crops go back in. Roots fork and go leafy in fresh manure, so they take the bed after the heavy feeders have used it.

Pests and problems for Salsify in Warm Temperate
Harvesting Salsify
When ready: Roots are at least 2-3cm diameter at the crown and 20-30cm long. White salsify: foliage begins to yellow in late autumn. Scorzonera: can be harvested in first year or left for a larger second-year harvest.
How to harvest: Dig deeply alongside the root with a fork (at least 30cm deep). Lift very gently. Salsify roots are thin, long, and snap extremely easily. Never pull by the foliage. Water the bed beforehand to soften soil. Cut foliage to 2cm. Do not scrub. Just brush off loose soil.
Storing and preserving salsify
How to keep it
- Refrigerator Storage. Wrap unwashed roots in damp paper towels inside a plastic bag. Store in crisper drawer. Keeps: 1-2 weeks.
- Freezing. Scrub, peel (salsify discolours rapidly, drop peeled pieces into lemon water immediately). Cut into chunks. Blanch 2-3 minutes. Ice bath, drain. Freeze on trays then bag. Keeps: 10-12 months.
- In-Ground Storage. Leave roots in the ground and harvest as needed through winter. Mulch for frost protection. This is the best method as roots deteriorate quickly once harvested. Keeps: 4-6 months in ground (through winter).
- Sand Storage. Harvest carefully. Do not wash. Layer in damp sand in boxes. Store at 1-4C in a dark, cool place. Keeps: 2-3 months.
